## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-engine-text-transform-pack-tier-2-828b6387 -d '<json body>'
```

Example prompt: Run this text through the ONE Engine tier-2 text transform and give me the result: 'The quick brown fox jumps over the lazy dog.'

## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call text transformation with x402 micropayments on Base and specifically need tier-2 processing semantics. It is ideal for autonomous agents that require programmatic text transformation at scale without subscription overhead.

## Known failure modes

- Missing or empty 'text' field returns an error response
- Payment not received via x402 results in 402 Payment Required
- Malformed JSON body returns a 400 Bad Request
- Text exceeding length limits may be rejected or truncated
- Network or Cloudflare Worker downtime causes 5xx errors

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object with a 'tier' field (value: 2) and a 'result' field containing the transformed text string after applying the tier-2 processing logic.
